  • Patent number: 10220217
    Abstract: A particular implantable device may include one or more antennas configured to receive a first far field radiative signal and a second far field radiative signal. The one or more antennas may be configured to receive the first far field radiative signal in a first frequency band and to receive the second far field radiative signal in a second frequency band. The implantable device may include a voltage rectifier configured to rectify the received first far field radiative signal and the received second far field radiative signal to provide a rectified voltage signal. The implantable device may further include a charge storage element operative to receive the rectified voltage signal and to store charge responsive to the rectified voltage signal. The implantable device may also include a therapy delivery unit powered by the charge storage element. The therapy delivery unit may be operative to deliver a therapy to a patient.

  • Patent number: 9522282
    Abstract: A system includes a first implantable medical device configured to receive a first far field radiative signal at a first frequency from an external transmitter to charge a first charge storage device. The first implantable medical device includes a first therapy delivery unit powered by the first charge storage device. The first therapy delivery unit delivers a first therapy to a first target tissue of a patient. The system also includes a second implantable medical device configured to receive a second far field radiative signal at a second frequency from the external transmitter to charge a second charge storage device. The second implantable medical device includes a second therapy delivery unit powered by the second charge storage device. The second therapy delivery unit delivers a second therapy to a second target tissue of the patient.

  • Patent number: 9259582
    Abstract: An implantable medical device may include a case which houses components of the implantable medical device. The implantable medical device may include an inductive coil coupled to a rechargeable battery. The inductive coil may be operative to inductively couple to an external coil and to transfer energy from the external coil to the rechargeable battery to recharge the rechargeable battery. The implantable medical device may include a cutout formed in the case of the implantable medical device and filled with a dielectric material. The cutout may be operative to reduce eddy currents in the case during recharge of the rechargeable battery. The implantable medical device may include a slot antenna disposed within the case. The slot antenna may be operative to communicate with an external device through the cutout in the case.
